    The reason and solution for the lawn mower stalling after refueling: How to choose engine oil for gasoline lawn mowers
    If a lawn mower is used for a long time without proper maintenance, it is easy to stall as soon as refueling is done. The reasons may be blocked oil circuits, blocked throttle valves, or abnormal spark plug ignition. This can be solved by checking the carburetor, exhaust pipe, carburetor main oil needle, and fuel tank cover and other accessories. The engine of a gasoline lawn mower is of utmost importance, and the choice of fuel is also crucial. There is a certain difference in the oil used for two-stroke and four stroke engines, and they cannot be mixed. Let's learn how to choose engine oil for a lawn mower.
    What is the reason for the lawn mower turning off when refueling
    1. In general, this situation is caused by blocked oil circuits, and when the throttle is increased, the mixture becomes too thin, causing the engine to run weakly and shut down. Suggest checking the carburetor.
    2. The throttle valve is blocked. The throttle valve is undoubtedly the most important component and also the most prone to problems. In general, maintenance personnel will consider cleaning the throttle valve. But if frequent cleaning of the throttle valve still cannot completely solve the stalling problem, it is generally considered a fault. Also, check the vacuum pump to see if the air intake is normal.
    3. Spark plug ignition is abnormal. When replacing spark plugs according to their service life, when a gasoline engine approaches the top dead center of compression, the combustible mixture is ignited by the spark plug. Therefore, when the spark plug malfunctions, it will naturally cause the vehicle to stall. Usually, the problem is completely solved by replacing the spark plug. When it is inconvenient to replace it, emergency measures such as cleaning the electrode and adjusting the length of the central electrode can also be taken to solve the problem. In addition, insufficient battery voltage, leakage, ignition coil failure, and circuit failure can all lead to poor ignition or stalling.
    How to solve it
    1. Check if the carburetor is blocked, causing insufficient oil intake. You can clean the carburetor or replace it.
    2. Check if the exhaust pipe is severely blocked. A two-stroke lawn mower is prone to this phenomenon. The exhaust can barely breathe with a small throttle, while the exhaust cannot be completely discharged with a large throttle, resulting in suffocation.
    3. Check if the main oil needle of the carburetor has fallen off. If it is a rotary throttle carburetor, it is possible that the oil level is too low. This phenomenon occurs when the engine is idling and a little throttle is applied, resulting in a lean mixture and stalling.
    4. Pay attention to whether the fuel tank cap is too tight or not, which prevents gasoline from flowing smoothly into the carburetor.
